EDWARD A. SANDERS, OF SAN FRANCISCO, CALIFORNIA.

HINGE.

Application filed November 15, 1913.

To all whom it may concern:

'Be it known that I, EDWARD A. SANDERS, a citizen of the United States, and aresident ofthe city and county of San Francisco, State of California, have invented certain new and useful Improvements in Hinges, of which the following is a specification. a

The invention relates to hinges and particularly to a complex hinge in which the movable part has a motion of translation as well as a motion of revolution.

The object of the invention is to provide a hinge in whichthe movable or pivotal part has a simultaneous movement of trans lation and rotation.

Another object of the invention is to provide a hinge which permits the movable structure attached thereto to be turned through an arc of 180 degrees.

A further object of the invention 1s to provide a hinge of such construction that the movable structure attached thereto lies in two parallel planes spaced apart from each other, for the two extreme positions of the hinge.

The invention possesses other advantageous features, which, with the foregoing, will be set forth at length in the following description, where I shall outline in full that form of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. The novelty of the invention will be included in the claims succeeding said description. From this it Will be apparent that I do not limit myself to the showing made by said drawings and description, as I may adopt many variations within the scope of my invention as set forth in said claims. I have designed the hinge to be used particularly in connection with reversible windows, where its use is of particular value, but it is evident that it may be used in many other instances and locations.

Referring to said drawings: Figure 1 is a front view of the hinge in the closed position. Fig. 2 is a sectional elevation of the hinge in the closed position taken on the line AA Fig. 1. Fig; 3 isa sectional elevation of the hinge in the open position, taken on the same line. Fig. 4 is a perspective view of the hinge partly open. Fig. 5 is a sectional elevation of a modified form of construction taken on the line B-..-B Fig.

as in the case of reversible windows.

reversible window showing the hinge of my invention in position.

The hinge of my invention is particularly adapted for use in locations or instances where a movement of the rotatable member through an arc of 180 degrees is desirable,

Reversible windows are usually made of the sliding sash type, so that they may be raised and lowered and the sliding sashes are fitted with pivoted or hinged sashes so that they may be turned or reversed for the purposes of cleaning or ventilation.

The hinge of my invention is especially adapted to be arranged between the sliding sash and the revoluble sash, although its use is not limited to such employment. For the purpose of convenience, however, and to illustrate one form of its use, I shall describe it in connection with a reversible window. The hinge, one of which is used on each side of the sash, is preferably embedded ina rabbet 2, which is secured to the side rail 3 of the sliding sash, and the movable part of the hinge is secured to the side rail 4 of the rotatable sash. As the rotatable sash is turned, the pivot is moved bodily in a direction transverse to the sash, so that the sash may be rotated through an arc of 180, a performance which is not possible with the hinges and pivots now in general use, on account of the angle or bevel of the upper and lower rails of the revoluble sash. In this specification, I shall refer to a rotatable sash, which is movable about a hori zontal axis, but it is to be understood that the hinge may be used with equal efficiency with a sash arranged to rotate on a vertical axis. With the use of my hinge, the sash does not occupy the same position in either of its positions, but the two positions are spaced from each other in the direction of the depth of the opening.

The hinge comprises a stationary member 5 which is attached by suitable means to a relatively stationary structure. Attached to the stationary member is a link 6 which carries the pivot or rotatable element 7, which is preferably formed as a square shaft or pin, which is secured to the rotatable structure,- The link 6 is so connected to the shaft 7 and to the stationary member 5, tha.t.a.r o:v

tation of the shaft causes a movement of the link with respect to the stationary member,

the rotation of the link being in'a lesser de The Figs. 1, 2, 3 and iand thenthe construction shown in Figs. 5, 6 and 7 In the first construction, the link 6 is pivotally attached to a'second link 8 which is pivoted .to the sta? tionary member adjacent one end. .Each of the links are formed of two members (i -6 and 8"-8 which are secured together by pins or the pivots, so that they each comprise an open frame. The pin or pivot 9 etween the two links is secured against rotation to the link 8, preferably by forming w. the ends of the pin square. The link 6 engages the pin 9., the sides 6 and 6 of the link preferably. lying between and in contact with'th'e sides 8 and 8 ofthe link 8. The outer surfaces of the side members 6 and 6? are cut away where these members fit between theimembers. S S", producing shoulders 12, which contact with .the upper edges of the members 8--8 when the hinge is closed, forming. stops. Secured to the fixed pin 9 is a gear 13 which meshes. with a gear 14 fixed 0n the shaft 7, so thata rotation of shaft 7 with respect to the link 6 causes a rotation of link 6.with respect to link 8. .Attached to the lower end of link 6,

orthat nd which lies within the link 8, is a pin 15 which engages in. aconcentric slot. 16

tionary member.

the side 8 of link Sand in'aneccentric slot or guide 17 in the stationary. member 5. The function of the slot 16 is to allow the pin to move in slot 17 which operates to rock the link 8 forward. and backward ,as. the shaft 7 is turned. hen the shaft 7 is turned ina clockwise direction the link ,6 turns in a clockwise direction with respect to the sta- The pin 15, contacting with the upper end of slot 17 stops. the movements. of translation and rotation of the shaft 7, in the present instance stopping, it after it has rotated through an arc of 180. The other end of the slot may act as a stop in the opposite direction, or the shoulders 12 mayserve as a stop for the link 6, or the flange or foot 19 mayserve as a stop for the link 8. All of the parts of the hinge are in frictional contact, so that some effort is required to rotate the shaft 7, and so that the parts will notlmove with respect to each other unless force is applied to the shaft 7.

In the structur shown in Figs. 5, 6 and 7,

the movement'of translation of the shaft .7

is accomplished by mounting the link 6 upon an eccentric pivot, which moves as the is the gear 14 which meshes with gear 13 which is fixed to the pin' or shaft '9 The shaft 9 passes through the side member and has secured on its end a gear 21 which meshes with a curved rack 22 on the stationary member 5. A pin 23 arranged concentrically with rotate about the pin 23,'ther.eby causing the link 6 to rotate about shaft. 9, which rotates about shaft 23. The resultant movement is substantially the same as that produced by the first described construction.
